To complement the increasing range of cnc systems for machine tools, kirloskar electric, in collaboration with indramat, germany, brought a complete range of dc feed and spindle drives. These spindle drives consists of pmdc motors in a wide range of 8 frames catering to 1 nm to 44 nm torque requirement with speed up to 3,000 rpm. The servo amplifiers are in the modules of 2 pulse thyristor amplifiers or transistorised pwm controllers. These servo amplifiers are y are available for one, two, three or four axes as packages. All control amplifiers are matched to the servo motors tthrough the use of systemate concept all control amplifiers are mathed to the servo motors. The main spindle range includes sseparately excited laminated yoke kldc motors to suit power requirements from 1 kw to 75 kw with speed controls ranging from 30 to 6,000 rpm is the main range of the spindle . The compact 6-pulse controller amplifier is optimised with kldc motor through the utilisation of systemate concept. Servo drive it is a four-quadrant regenerative drive and has built-in diagnostic features. Further, kkeeping in tradition of upgrading technology, kirloskar electric has manufactured built the first indigenously developed tripezoidal synchronous brushless dc [ac servo] motors and controllers. These motors and controllers have been constructeddesigned based uponon the experience of manufacturing machine tool drives for the past decade. The total package of ac drive includesconsists of ac servo motors, ac servo controllers and auto transformers. Thise package covers a total range of torque requirements from 3.5 nm to 38 nm up to 3,000 rpm. The total system is designed tto suit indian environment and power supply condition this system is designed. The system and is based on systemate concept. The salient features of servo drives includeare maintenance-free brushless motors, ip65 protection, class-f insulation, built-in thermal switch, igbt based power section, high operating frequency, diagnostic and status indication, and extensive protection circuitry.
